【摘要】：儲能系統(tǒng)既能作為電源,又可以作為負荷,在微網(wǎng)中起著雙向調(diào)節(jié)的重要作用。隨著微網(wǎng)中儲能技術(shù)的應用,級聯(lián)多電平變換器作為一種新穎的儲能功率調(diào)節(jié)系統(tǒng)(PCS)開始被廣泛研究。級聯(lián)儲能變換器的H橋直流鏈電流包括直流分量與紋波電流分量,紋波電流分量會對電池儲能系統(tǒng)性能產(chǎn)生不利影響。論文首先研究了H橋直流鏈電流中紋波電流形成的機理,建立了H橋紋波電流電路模型,研究了直流鏈紋波電流的傳輸特性與影響因素;在此基礎上提出了基于直流有源濾波器(DC-APF)的級聯(lián)儲能變換器電路拓撲,研究了利用直流有源濾波器抑制H橋直流鏈紋波電流的控制策略,最后通過仿真顯示了該方法的有效性。
[Abstract]:Energy storage system can be used as both power supply and load, which plays an important role in bidirectional regulation in microgrid.With the application of energy storage technology in microgrid, cascaded multilevel converters have been widely studied as a novel energy storage power regulation system (PCS).The H-bridge DC chain current of cascaded energy storage converter consists of DC component and ripple current component, and the ripple current component will adversely affect the performance of battery energy storage system.Firstly, the mechanism of ripple current formation in H bridge DC chain current is studied, the circuit model of H bridge ripple current is established, and the transmission characteristics and influencing factors of DC chain ripple current are studied.On this basis, the topology of cascaded energy storage converter based on DC active filter (DC / APF) is proposed, and the control strategy of suppressing the ripple current of H bridge DC chain by using DC active power filter is studied. Finally, the effectiveness of the method is demonstrated by simulation.
